The Talon tool is designed for rapid cleaning of the chamber locking lugs and lug recesses in AR type semi-auto rifles. It"s a lug pick that scrapes all eight lugs at once. Debris are trapped inside its recesses for immediate removal. Talon was developed to rapidly remove carbon, sand, or brass shavings from the lug area, without the use of solvent, in the field. It also makes a good tool to use ahead of a chamber mop and solvent during regular cleaning. The C.A.T. M4 tool addresses the critical areas of the bolt and bolt carrier assembly and the carbon buildup that collects on the operating surfaces during prolonged firing. The C.A.T. M4 tool is a lightweight simplistic tool that has five functions in one compact rugged field ready design and it is totally American manufactured.
